Kerosene heater



Patented Jan. 19, 1926.-

UNITED STATES PAUL ADOLF KAYSER, OF SAN FRANCISCO, CALIFORNIA.

KEROSENE HEATER.

Application filed August 15, 1925.

To all whom it may concern:

Be it known that PAUL Anew KAYSER, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, has invented certain new and useful Improvements in KeroseneHeaters, of which the following is a specification.

This invention pertains to kerosene heaters and has as its specialobject the construction of a case wherein means are devised which willkeep the kerosene reservoir in an upright position even though theheater be upset or turned upside down.

Another object is to provide in a novel manner a wick screw which willnot interfere with the operation of the kerosene reservoir.

Other objects will be apparent from the accompanying drawing andspecification.

In the drawing- Figure 1 is a vertical section of the kerosene heatercase showing the kerosene reser voir mounted therein.

Figure 2 is a horizontal section of the kerosene heater case showing thekerosene reservoir and wick screw.

Figure 3 is a vertical section of the kerosene heater case upset, thekerosene reservoir being in a vertical position.

In carrying out this invention I provide an outer casing 1 of usualconstruction and having provided in its lower half 2 bearings 3 thruwhich threaded pins 4 having reduced pivot points 5, are passed. Thesaid bearings 3 are mounted directly opposite each other and on the samehorizontal plane. A fiat metal ring 6 having bearings 7 incorporatedtherein and apertures 8 pierced therein, is pivotally mounted upon thepivot points 5 of the threaded pins 4. Passed thru the bearings 7 arethreaded pins 9 having reduced pivot points 10 which are adapted toengage pivot bearings 11 that are secured to the kerosene reservoir 12.The bearings 7 are formed directly opposite each other at right anglesto the apertures 8, and have all their center lines on the samehorizontal plane, so that when the kerosene reservoir 12 is assembled inthe casing 1 it will be perfectly aligned and balanced, so that theslightest tipping of the said casing will cause the said reservoir 12 toswing into a vertical position and Serial No. 50,380.

thus eliminate all danger of spilling kerosene when the heater is upsetand possibly starting a fire.

In order to permit raising or lowering the wick as desired withoutundermining the principle as above described, a rather novel arrangementhas been devised, which consists in mounting upon the wick screw shaft13 the one half 14 of a jaw clutch. The other half 15 of the said jawclutch is mounted upon a shaft 16 which is journaled in a bearing 17that is secured to the outer side of the lower half 20f the casing 1. Acoil spring 18 is mounted over the shaft 16 and is adapted to bearagainst the casing 1 with one end and against a hand wheel 19 which ismounted at the outer extremity of the shaft 16 with the other end. Whenit is desired to raise or lower the wick, pressure is brought againstthe hand wheel 19 until the half 15 of the jaw clutch engages the half14, whereupon the said hand wheel 19 is turned in the desired direction.WVhen the pressure upon the hand wheel 19 is released, the coil spring18 will throw out the clutch and return the shaft 16 to its normalposition.

While I have herein described. a certain specific method of constructingand assembling the elements of my invention, it is understood same maybe varied in minor details, not departing from the spirit of myinvention as defined in the appended claim.

I claim:

In a kerosene heater as described, embodying a case, a kerosenereservoir in said case; bearings for said case; threaded pins withreduced pivot points engaging said bearings; a fiat ring pivoted on saidpivot points; bearings formed in said fiat ring; pivot bearings for saidkerosene reservoir; threaded pins with reduced points secured in thebearings of said flat ring, engaging the pivot bearings of said kerosenereservoir; a wick screw shaft for said kerosene reservoir; the half of ajaw clutch mounted on said wick screw shaft; a bearing on the outer sideof said case; a shaft journaled in said bearing; the other half of saidjaw clutch on said shaft; a coil spring on said shaft; and a hand wheelfor said shaft.

In testimony whereof I afiix my signature.

PAUL ADOLF KAYSEB.
